There are all kinds of good books out there now for this very thing. I work in a native flower greenhouse and we do this sort of thing all the time. First you need to know what type of soil you have...is it dry...wet or medium(mesic). Next do you have alot of shade or is it all sun or a mix. Here is a list of plants : Monarda fistulosa (wild bergamont) sunny....mesic/dry Petalostemum purpureum (purple prairie clover) sunny--dry
Aquilegia canadensis (columbine) part shade.....mesic
Blazing stars....(there are many different varieties for different areas)
Asclepias Tuberosa(butterfly weed)...sunny...dry...sand
Asclepias Incarnata (red milkweed)...sunny/part shade...wet..mesic
Bouteloua curtipendula(side oats gramma) sunny...dry
Schizachryum scoparium(little bluestem) sunny....dry
Viburnum triloba (american cranberry) part sun/shade...mesic soil...birds love the berries
Sambucus canadensis(elderberry)......part sun/shade...mesic soil birds love the berries
Agastache foeniculum(anise hyssop) sun/part shade.....dry to mesic
Penstemons....different ones but birds and insects love them
Zizia's....there is one for wet areas and one for dry ...insects love them
Rudbeckia Submentosa(sweet black-eyed susan) sun....dry
There are tons more but this is a simple list to get you started.....
Hope it helps....
